Commissioning (installation and configuration) Micropilot FMR62
18 Endress+Hauser
The following parameters affect the safety function. If the settings differ from the as-
delivered state of the device, only the expert mode can be selected during SIL/WHG
confirmation. It is not possible to specify values because the as-delivered state of the
device depends on the order code.
"Setup" menu
• Advanced setup → Level → Medium type
• Advanced setup → Current output 1 → Current span
• Advanced setup → Current output 2 → Current span
"Expert" menu
• Sensor → Distance → Blocking distance evaluation mode
• Sensor → Envelope curve → Envelope curve statistic
• Sensor → Envelope curve → Envelope smoothing mode
• Sensor → Envelope curve → FAC window size
• Sensor → Envelope curve → Max Value EWC
• Sensor → Sensor properties → Antenna zero distance
• Sensor → Mapping → Mapping Threshold
• Sensor → Mapping → Mapping window size
• Sensor → First echo factor → First echo factor
• Sensor → Echo fine adjustment → Parabolic fit window size
• Sensor → Echo fine adjustment → Edge correction
• Sensor → Tank bottom evaluation → Tank bottom range
• Sensor → Echo tracking → Moving track recognition
The following parameters affect the safety function. If the settings differ from the
permitted values indicated, SIL/WHG confirmation is canceled automatically, and the
device cannot be locked in either the increased safety mode or in the expert mode.
"Setup" menu
• Advanced setup → Current output 1 → Assign current output
• Advanced setup → Current output 1 → Failure mode = Min. or Max.
"Expert" menu
• Output → Current output 1 → Assign current output
• Output → Current output 1 → Start-up mode = Min. or Max.
• Communication → Output → Assign PV
• Those parameters which are not mentioned do not affect the safety function and
can be configured to any meaningful values. The visibility of the parameters
mentioned in the operating menu depends in part on the user role, the SW options
ordered and on the configuration of other parameters.
• In the SIL mode, the device must not be operated in HART-Multidrop mode, as
otherwise the current output will assume a fixed value. For this reason, only the
setting "Expert → Communication → Configuration → HART address = 0" is
permitted in the SIL mode and in the combined SIL/WHG mode when the device is
in the increased safety mode. In pure WHG mode, HART Multidrop is permitted in
the expert mode as long as the HART signal is evaluated in an external switching
unit (e.g. Tank Side Monitor NRF590) that complies with the approval principles as
per WHG.
